Produits neutres et alcaloides de Myrtopsis macrocarpa, M. myrtoidea, M. novae-caledoniae et M. sellingii☆

Abstract Stems and leaves of Myrtopsis macrocarpa , M. myrtoidea , M. novae-caledoniae and M. sellingii yielded terpenes, sterols, coumarins, alkaloids (furoquinolines and quinolones) and amides. A new quinolone (8-methoxy flindersine) occurs in Myrtopsis macrocarpa , a new amide ( N -benzoyltryptamine) in M. myrtoidea , two new coumarins (myrsellin and myrsellinol) and a new dihydrofuroquinoline (myrtopsine) in M. sellingii . Structures of the new compounds are proposed from chemical and spectroscopic evidence.
